To all who 117, 56 may concern:

Be it known that I, EARL H. SHEiiBoivDY,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Turbine-Casings, of which the following is a specification. I i

This invention relates to a turbine casing for a turbine that is designed to be operated by the waste gas from an internal combustion engine.

It is an object of the invention to produce a casing of a few simple parts, of simple shape, that may be readily stamped out of sheet metal, which will permit of rapid production and easy assemblage of the parts.

The casing in question is of a structure similar to that disclosed in my co-pending application, Serial No. 226289, filed April 2, 1918.

In the drawings representing a possible embodiment of my invention, Figure 1 is a side view, partly in section of the turbine casing; Fig. 2 is a similar view, taken at right angles thereto, and Fig. 3 is an end View of Fig. 1.

The turbine 1 carries the usual buckets 2, and rotates on the usual shaft 3. The side wall of the casing is formed by an annular portion 4:, which is stamped out of sheet metal and flanged at 5 and 6. This portion 4 is of a frusto-conical shape. This portion 1 may be provided with exhaust pipes 7 and 8, integral therewith, and is flanged as at 9,-

for the attachment of exhaust pipes 10.

The front wall of the casing is formed by a piece of sheet metal, comprising a substantially cylindrical portion 11, which is bent outwardly to merge into disk-like portion 12, at substantially right angles thereto, the portion 12 being flanged at 13.

The back plate 14 of the casing is of sheet metal, is attached to the flange 5 of the side wall 1, and is bent, as at 15, toward the buckets 2.

The diaphragm 16, of a generally conical shape, is bent at its outer edge, as at 17, the

part 17 being clamped and held in position between the described flanges 6 and 13. The front plate and diaphragm define an inlet chamber 18 for the gases that are to operate the turbine. The inner edges of the annular portion 11 of the front plate and of the diaphragm 16 converge toward one another, and have positioned between the converging Specification of Letters Patent.

portions, nozzles or a nozzle ring 19, for directing the gas into the buckets of the turbine.

The diaphragm 16 may have one or more valve seats 20, drawn out integrally therefrom to provide a seat for a by-pass valve 21, which valve may be operated by any suitable means.

The diaphragm 16, back plate 14 and side wall 1 define an exhaust chamber 22, from which exhaust chamber the gases pass outwardly and escape through the exhaust pipes 7 and 8. i

The portion 12 of the front plate may have drawn integrally therefrom, inlet pipes 23, which may be flanged as at 24. The course of the gas through the apparatus is indicated with the arrows.

The parts of the casing are intended to be stamped out of sheet metal, and thus permit rapid production and assemblage.

While I have illustrated a possible em bodiment of my invention, it should be understood that it may be carried out in other ways, as defined within the scope of the appended claims.

I claim 1. A turbine casing, comprising an annular element forming the side Wall, a front plate and a diaphragm clamped between said element and said front plate to define inlet and exhaust chambers.

2. A turbine casing, comprising an annular element forming the side wall, a front plate and a diaphragm clamped between said element and said front plate to define inlet and exhaust chambers, said diaphragm also cooperating with said annular front plate to act as nozzle holding means.

3. A turbine casing, comprising an annular element forming the side wall, a front plate comprising a substantially cylindrical portion merging into a disk-like portion substantially perpendicular thereto and a diaphragm fastened to said annular element and the disk-like portion, the front plate and said diaphragm defining an inlet chamber.

4. A turbine casing, comprising an annular element forming the side wall, a front plate and a diaphragm clamped between said element and said front plate to define inlet and exhaust chambers, said diaphragm being provided with valve seats integral therewith.

5. A turbine casing, comprising an annular element forming the side wall, a front plate and a conically shaped diaphragm, clamped between said annular element and clamped between said annular element and saidfront plate, said diaphragm and said 10 said front plate, said diaphragm and said front plate defining an inlet chamber befront plate defining an inlet chamber between them, and converging to define a noz- 5 tween them. zle seat between them.
